Description

Title of the invention: Method and device for controlling a vehicle's stability and traction control system technical field

[0001] The invention relates to methods and devices for controlling a vehicle's stability and traction control system, particularly for automobiles. The invention specifically relates to a method and device for displaying additional information for a vehicle's stability and traction control system. The invention also relates to a method and device for assisting with vehicle driving. Technological background

[0002] Contemporary vehicles include, for some of them, several screens to display information useful to the driver for driving the vehicle as well as comfort information, such as, for example, information to interact with the infotainment system, also called IVI system (from the English "In-Vehicle Infotainment" or in French "Infodivertissement étoilé"), of the vehicle.

[0003] Among these screens, it is known to include one or more LCD type screens (from the English "Liquid Crystal Display" or in French "Affichage à cristals liquide"), for example of type TFT (from the English "Thin-Film Transistor" or in French "Transistor en film mince"), or OLED (from the English "Organic Light-Emitting Diode" or in French "Diode électroluminescente organique").

[0004] The integration of such screens makes it possible, for example, to control, via a graphical Human-Machine Interface (HMI) displayed on such screens, the operating status of the systems on board the vehicle, for example AD AS systems (from the English "Advanced Driver-Assistance System" or in French "Système d'aide à la conduite avancé").

[0005] The increasing number of embedded systems in the vehicle and the proliferation of means for controlling these systems lead to a greater complexity in the vehicle's interface. This complexity arises when a user interacts with the embedded systems to control them, particularly with the proliferation of icons, displayed messages, and command shortcuts, the control and management of which are consequently complicated for the user. The user experience is thus degraded, and the driver's attention may be reduced when various messages are displayed on the vehicle's screen(s).

[0006] For example, for vehicles equipped with a stability control system and The traction control system, also known as CDS (Dynamic Stability Control, also called CDS / ASR, where ASR stands for Anti-Slip Regulation), displays several warning lights or messages depending on the current status of the CDS system, for example, when the CDS system encounters a problem, to alert the driver. The proliferation of displayed messages, combined with the use of warning lights or icons unfamiliar to most drivers, degrades the user experience and can distract the driver, which can be dangerous for the vehicle and its passengers. Summary of the present invention

[0007] One object of the present invention is to solve at least one of the problems of the technological background described above.

[0008] Another object of the present invention is, for example, to improve the control of a vehicle's stability and traction control system, in particular a motor vehicle.

[0009] Another object of the present invention is, for example, to improve the user experience with regard to the control of this stability and traction control system.

[0010] Another object of the present invention is, for example, to improve safety in a vehicle.

[0011] According to a first aspect, the present invention relates to a method for controlling a stability and traction control system, known as a CDS system, of a vehicle, the vehicle having a display system including a touch screen, the method comprising the following steps: - control of display of a signal indicator representative of the CDS system in a determined content of a human-machine interface, known as HMI, displayed in a first area of ​​the touch screen; - reception of initial data representative of an initial touch on the signal indicator; - control of display of a first graphic content including at least one piece of information representative of a current state of the CDS system following the reception of the first data, the first graphic content being displayed in a second area of ​​the touch screen different from the first area.

[0012] Direct use of the indicator light representing the CDS system to request the display of additional content related to the CDS system, for example, the current status of the CDS system, allows the driver to obtain additional information on demand by touching the indicator light. This reduces the unintended display of content not desired by the driver, who controls the display of this content on demand. Furthermore, all the content is displayed on a single screen, which facilitates access to information and minimizes search time. Information. This improves driver vigilance, as well as the safety of the vehicle and its passengers.

[0013] Centralizing controls on a single screen also eliminates the need for physical buttons to control the CDS system, thus reducing vehicle design and manufacturing costs.

[0014] According to one variant, the signal indicator is displayed according to a determined graphic representation from a set of graphic representations, the determined graphic representation being a function of the current state of the CDS system.

[0015] According to another variant, the current state belongs to a set of states comprising: - an activated state; - a disabled state; and - a failing state.

[0016] According to a further variant, the process further comprises the following steps: - reception of second data representative of a second touch press on the signal indicator, the second touch press being subsequent to the first touch press; - control of the end of display of the first graphic content in the second area following the reception of the second data.

[0017] According to yet another variant, the display control of the first graphic content is triggered when the first touch press corresponds to a touch press of a duration less than a threshold.

[0018] According to an additional variant, the end-of-display control of the first graphic content is triggered when the second touch press corresponds to a touch press of a duration less than the threshold.

[0019] According to another variant, the method further comprises the following steps: - receiving third data representative of a third touch press on the signal indicator, the third touch press corresponding to a touch press of a duration greater than the threshold; - display control of a second graphic content including at least one graphic object configured to control at least one parameter of the CDS system following the reception of the third data.

[0020] According to a second aspect, the present invention relates to a control device for a vehicle stability and traction control system, the device comprising a memory associated with a processor configured for the implementation of the steps of the process according to the first aspect of the present invention.

[0021] According to a third aspect, the present invention relates to a vehicle, for example a motor vehicle, comprising a device as described above according to the second aspect of the present invention or a system as described above according to the third aspect of the present invention.

[0022] According to a fourth aspect, the present invention relates to a computer program which includes instructions adapted for carrying out the steps of the process according to the first aspect of the present invention, in particular when the computer program is executed by at least one processor.

[0023] Such a computer program may use any programming language, and be in the form of source code, object code, or an intermediate form between source code and object code, such as in a partially compiled form, or in any other desirable form.

[0024] According to a fifth aspect, the present invention relates to a computer-readable recording medium on which is recorded a computer program comprising instructions for carrying out the steps of the process according to the first aspect of the present invention.

[0025] On the one hand, the recording medium can be any entity or device capable of storing the program. For example, the medium can include a storage means, such as a ROM, a CD-ROM or a microelectronic circuit-type ROM, or a magnetic recording means or a hard disk drive.

[0026] On the other hand, this recording medium can also be a transmissible medium such as an electrical or optical signal, such a signal being able to be transmitted via an electrical or optical cable, by conventional or radio frequency, by self-directing laser beam, or by other means. The computer program according to the present invention can, in particular, be downloaded from an Internet-type network.

[0027] Alternatively, the recording medium may be an integrated circuit in which the computer program is incorporated, the integrated circuit being adapted to execute or to be used in the execution of the process in question. Brief description of the figures

[0036] A method and a control device for a vehicle stability and traction control system, referred to as a CDS system, will now be described in the following with joint reference to Figures 1 to 7. The same elements are identified with the same reference signs throughout the following description.

[0037] The terms "first," "second" (or "firsts," "seconds"), etc., are used in this document by arbitrary convention to allow for the identification and distinction of different elements (such as operations, means, etc.) implemented in the embodiments described below. Such elements may be distinct or correspond to a single element, depending on the embodiment.

[0038] According to a particular and non-limiting embodiment of the present invention, the control of a vehicle's stability and traction control system, referred to as the CDS system, is implemented, for example, by one or more vehicle control units. To this end, the method includes controlling the display of an indicator light representing the CDS system. The indicator light corresponds, for example, to a symbol or pictogram representing the CDS system, or a current state of the CDS system, and is displayed in a first area or part of a vehicle touchscreen within a specific content of a human-machine interface, referred to as the HMI, for example, on a specific page of the HMI corresponding, for example, to the home screen or the default screen of the HMI.Initial data representing a touch input on the displayed indicator light is received from the touch interface, for example, when a user touches the touchscreen at the indicator light's display location. Following the reception of the... Based on initial data, the computer controls the display of graphic content including at least one piece of information representing the current state of the CDS system in a second area of ​​the touch screen different from the first area.

[0039] Such a method makes it possible to control, via a voluntary action, the display of information relating to a current state of the CDS system.

[0040] A vehicle stability and traction control system is known by various names such as ESP (Electronic Stability Program), ESC (Electronic Stability Control), DSC (Dynamic Stability Control), VSC (Vehicle Stability Control), DSTC (Dynamic Stability and Traction Control) or VSA (Vehicle Stability Assist).

[0041] Such a stability and traction control system corresponds to an electronic stability control system. This system acts on the brakes to enhance vehicle grip and limit stability loss on the road. One of the objectives of such a CDS system is to ensure continuous tire grip on the road surface. The CDS system uses the vehicle's hydraulic braking system to slow one or more wheels and thus apply forces to the car in a direction determined by an electronic system that reacts to sensors, such as the yaw sensor, the steering wheel angle sensor, and the wheel speed sensors. The wheel sensors indicate the wheel rotation, the yaw sensor provides the trajectory followed by the car, and the steering wheel sensor determines the direction the driver intends to give the vehicle.If the vehicle deviates from the intended trajectory, the computer commands the braking of one (or more) wheel(s) which will correct the trajectory by pivoting the vehicle's body.

[0042]

[0043] Fig. 1 schematically illustrates part of the passenger compartment of a vehicle 10, according to a particular and non-limiting embodiment of the present invention.

[0044] Vehicle 10 corresponds, for example, to a vehicle with an internal combustion engine, with electric motor(s), or even a hybrid vehicle with an internal combustion engine and one or more electric motors. Vehicle 10 thus corresponds, for example, to a land vehicle comprising a passenger compartment or at least equipped with a display screen, for example, a car, a truck, a bus, a motorcycle.

[0045] The vehicle 10 advantageously incorporates a display system comprising a touchscreen 13 and a computer configured to control the display of content(s) of a graphic HMI on the touch screen 13. The computer corresponds for example to the computer of the infotainment system, called IVI computer (from the English "In-Vehicle Infotainment" or in French "Infodivertissement étoilé") of the vehicle 10.

[0046] According to a particular embodiment, the display system includes one or more other screens, for example a screen of a device or system called a head-up display corresponding for example to a transparent or semi-transparent blade arranged in such a way that a driver sitting in the seat 15 sees the content displayed or projected onto the transparent blade when the driver drives the vehicle 10.

[0047] Such a display system including the touch screen 13 is for example provided or configured to reduce the number of screens present in the vehicle 10, allowing for example the removal of the display screen(s) called instrument cluster or instrument panel and generally arranged in an area 13 behind the steering wheel 14 in the dashboard 11.

[0048] According to a particular embodiment, the vehicle 10 carries one or more embedded systems, each controlled by one or more computers. These computers, together with the IVI computer, form, for example, a multiplexed architecture for providing various services useful for the proper functioning of the vehicle and for assisting the driver and / or passengers of the vehicle in controlling the vehicle 10 via the control of the embedded system(s) in the vehicle 10.Computers communicate and exchange data with each other via one or more computer buses, for example a CAN (Controller Area Network), CAN FD (Controller Area Network Flexible Data-Rate), FlexRay (according to ISO 17458), LIN (Local Interconnect Network), or Ethernet (according to ISO / IEC 802-3) type communication bus.

[0049] The system(s) on board the vehicle 10 correspond, for example, to a stability control and traction control system, denoted CDS system. The vehicle 10 also carries, for example, an anti-lock braking system, known by the acronym ABS (from the German "Antiblockiersystem").

[0050] A control process of the vehicle 10 CDS system is advantageously implemented by the vehicle 10, for example by one or more processors of one or more computers of the vehicle 10 on-board system, for example by the IVI computer.

[0051] In a first operation, the display of a warning light representative of the vehicle's CDS system 10 is controlled in such a way that the warning light lisation is displayed on the touch screen 13 in a determined content of a human-machine interface, called HMI, which content is displayed on the touch screen 13.

[0052] The displayed content includes, for example, a set of information useful to the driver to ensure control and supervision of the vehicle 10.

[0053] The information set includes, for example, the instantaneous speed of the vehicle 10 when the latter is in a driving or traffic phase, that is to say in motion, driven by the engine of the vehicle 10.

[0054] The information set includes, for example, other supplementary information such as, for example, the remaining range (expressed for example in kms), the distance traveled, a level of energy remaining in the tank (for example, the amount of electrical energy remaining in the traction battery when the vehicle 10 corresponds to an electric vehicle or the amount of fuel remaining in the tank when the vehicle 10 is a vehicle with an internal combustion engine), etc.

[0055] The displayed indicator light is, for example, representative of a current state of the CDS system. The graphical representation of the displayed indicator light depends, for example, on the current state of the CDS system and belongs to a specific set of graphical representations.

[0056] The current state of the CDS system corresponds for example to one of the following states: activated state, deactivated state or faulty state.

[0057] For example, the indicator light displays according to a first graphic representation determined when the CDS system is activated, i.e., when the vehicle's stability control and traction control function is activated and in operation. The indicator light displays, for example, according to a second graphic representation when the CDS system is deactivated, for example, following a manual and deliberate action by the driver who wishes to deactivate the vehicle's stability control and traction control function 10. The indicator light displays, for example, according to a third graphic representation when the CDS system malfunctions, i.e., when the CDS system encounters a problem and the vehicle's stability control and traction control function 10 is no longer functioning.

[0058] The warning light is, for example, graphically identical in the first and second graphic representations, with only the color of the light varying between them. The third graphic representation, for example, differs graphically from the first and second graphic representations, the light in the third graphic representation being, for example, the same visual element as the light in the first and second graphic representations, adding, for example, a pictogram (such as a wrench) to the pictogram of the light in the first and second graphic representations. first and second graphic representations.

[0059] The indicator light 211, according to the first or second graphic representation, is illustrated, for example, in [Fig. 2]. [Fig. 2] illustrates an example of the display of the indicator light 211 in a first part or defined area 21 of the touchscreen 13. The first defined area 21 is, for example, assigned or dedicated for displaying content from the HMI controlled by the IVI computer to provide or display to the driver the information necessary for controlling the vehicle 10, for example, the instantaneous speed.

[0060] The signal indicator 211 representing the CDS system corresponds for example to a symbol defined in a standard, for example an ISO standard.

[0061] The warning light 211 shown in [Fig. 2] is, for example, displayed according to a first predetermined graphic representation representing an activated state of the CDS system, the warning light 211 then being represented in a first predetermined color (for example, gray or grayish). According to another example, the warning light 211 is displayed according to a second predetermined graphic representation representing a deactivated state of the CDS system, the warning light 211 then being represented with the same pictogram as for the first graphic representation but with a second predetermined color different from the first color (for example, orange or red). The pictogram associated with the warning light 211 represents, for example, a vehicle with two "S"-shaped lines under the vehicle symbolizing a skid or loss of traction, with the word "OFF" (meaning "off" in English) below the "S"-shaped lines.Thus, the color associated with indicator 211 according to the first representation (in grey or gray) indicates that the system is in the activated state (or "ON" in English) and the color associated with indicator 211 according to the second representation (in orange or red) indicates that the system is in the deactivated state (or "OFF").

[0062] The first zone 21 covers, for example, only a part of the total display area of ​​the screen 21, one or more other determined zones (not illustrated) being, for example, assigned to other HMI content, for example, a zone to display information associated with the vehicle multimedia system 10 and / or a zone to display information associated with the vehicle navigation system 10.

[0063] In a second operation, first representative data of a first touch 212 on the signal indicator 211 are received, following a touch 212 by a user (for example the driver of the vehicle 10) on the signal indicator 211.

[0064] A touch 212 on the indicator 211 sends information to the IVI control unit so that the latter implements a function associated with the command corresponding to the touch press.

[0065] The first representative data of the touch press are received for example via one or more data buses linking the touch interface of the screen (or a computer controlling such a touch interface where applicable) and the IVI computer.

[0066] The first data are for example representative of a so-called brief touch, that is to say, whose duration of pressing on the witness 211 is less than a threshold duration (for example equal to 500 or 1000 ms).

[0067] According to another example, the first data are representative of a double click, that is to say a sequence of two consecutive and close touch presses (with for example less than 250 or 500 ms between the two consecutive touch presses).

[0068] In a third operation, the IVI control unit controls the display of initial graphic content comprising one or more pieces of information representative of the current state of the CDS system. This initial graphic content is displayed in a second zone 31 of the touchscreen 13, as illustrated in [Fig. 3], which second zone 31 is distinct from the first zone 21 in which the indicator 211 is displayed. The display of the initial graphic content in the second zone 31 is triggered by the reception of the initial data.

[0069] The first graphic content is, for example, displayed in a window occupying part of the display area of ​​screen 13 and corresponding to the second zone 31, this window corresponding, for example, to a contextual window, also called an intrusive or pop-up window. This window is, for example, displayed next to the first zone 21, for example centered on the screen (around the center of screen 13).

[0070] According to an example embodiment illustrated in [Fig.3], the first graphic content displayed on the second area of ​​the screen 31 includes, for example, a text area 311 for displaying text explaining the current state of the CDS system.

[0071] Thus, when indicator 211 is displayed according to the first graphic representation, the text displayed in area 311 indicates that the CDS system is active or activated. When indicator 211 is displayed according to the second graphic representation, the text displayed in area 311 indicates that the CDS system is inactive or deactivated.

[0072] According to one embodiment, the first graphic content further includes additional information 312 associated with the text in the text box, this additional information taking, for example, the form of an icon or pictogram specifically illustrating the current state of the CDS system. For example, when indicator 211 is displayed according to the first graphic representation, the additional information 312 corresponds to a pictogram representing the indicator of the CDS system but without the word "OFF" to clearly illustrate that the system is in the activated state. When indicator 211 is displayed according to the second graphic representation, the additional information 312 corresponds to a pictogram corresponding to the indicator representing the CDS system with for example a triangle surrounding the word "OFF" (or with the word "OFF" flashing) to draw the driver's attention to the fact that the CDS system is deactivated.

[0073] Fig. 4 illustrates the display of screen 13 with the signal indicator displayed according to the third graphic representation 411, in the first zone 21, representative of a current state corresponding to a faulty state of the CDS system.

[0074] A touch 412 (for example, a brief touch) on this indicator 411 triggers the display control of graphic content similar to the first graphic content illustrated in [Fig. 3]. This similar graphic content is shown according to a particular embodiment in [Fig. 5].

[0075] This first graphic content associated with the faulty state of the CDS system also includes one or more pieces of information representative of the current state of the CDS system, i.e. the faulty state. This first graphic content is displayed in a second zone 51 different from the first zone 21, corresponding for example to the second zone 31 of [Fig. 3].

[0076] The first graphic content 51 also includes, for example, a first piece of information corresponding to a text displayed in a text area 511 explaining that the CDS system is faulty and that it is necessary to approach or contact a service center to have a diagnosis or repair carried out.

[0077] A second piece of information 512 is, for example, also displayed in addition to the first piece of information 511, this second piece of information taking, for example, the form of a video animation illustrating a person repairing the vehicle 10.

[0078] According to one embodiment, the first information 511 further includes when the cause of the malfunction of the CDS system (for example sensor problem).

[0079] According to one embodiment, the process further comprises a fourth operation in which second data representing a second touch press on the signal indicator 211 or 411 are received, following a touch press by a user (for example the driver of the vehicle 10) on the signal indicator 211 or 411.

[0080] This second touch press, which is temporally subsequent to the first touch press 212 or 412, sends information to the IVI computer so that the latter can implement a function associated with the command corresponding to this second touch press.

[0081] The second data are for example representative of a so-called brief touch press, that is to say, whose duration of pressing on the witness 211 or 411 is less than the threshold duration (for example equal to 500 or 1000 ms) defined previously.

[0082] This second touch press corresponds to a touch press performed while the first graphic content is displayed in the second zone 31 or 51 of the screen (and that the The second touch press corresponds to a short press.

[0083] In a fifth operation, the end of the display of the first graphic content is controlled so that the first graphic content is no longer displayed in the second area 31 or 51 of the screen 13 following the reception of the second data.

[0084] The graphic content displayed before the reception of the first data representing the first touch press 212 or 412, that is to say before the display of the first graphic content, is then for example displayed again in the second zone 31 or 51. When the second zone 31 or 51 corresponds to a pop-up window, then this pop-up window is closed.

[0085] According to one embodiment, the display ends automatically via the computer after a predetermined time period that begins when the first graphic content is displayed. For example, this predetermined time period is such that the first graphic content remains displayed for, say, 5, 10, or 15 seconds and then disappears automatically, even without the user performing a second touch.

[0086] According to a particular embodiment of the invention, the process further comprises receiving third data points representing a third touch press on the indicator light 211 or 411, the third touch press corresponding to a touch press lasting longer than the threshold. These third data points are representative of a so-called long touch press (i.e., lasting longer than the threshold duration defined previously (for example, equal to 500 or 1000 ms)).

[0087] A long touch press on indicator 211 or 411 sends information to the IVI computer so that the latter implements a specific function associated with the command corresponding to this long touch press.

[0088] The reception of the third data triggers an operation to control the display of a second graphic content by the computer.

[0089] The reception of the third data triggers, for example, the display of the second content in a pop-up window, for example next to the first area 21.

[0090] The second graphic content comprises one or more graphic objects, each configured to control a parameter of the CDS system. The graphic object(s) of the second graphic content are, for example, a function of the current state of the CDS system; for example, the graphic object(s) vary depending on whether the warning light 211 is displayed according to the first graphic representation (representing the activated state of the stability control and traction control function) or according to the second graphic representation (representing the activated state of the stability control and traction control function).

[0091] Thus, when the indicator 211 is displayed according to the first graphical representation (corresponding to the current activated state), a displayed graphical object is configured for Automatically deactivate the stability control and traction control function. Confirmation of switching to automatic deactivation mode is obtained, for example, by touching this graphic object (for example, on a button taking 2 states, 1 state corresponding to automatic deactivation activated and 1 state corresponding to automatic deactivation deactivated), by voice command or by activating a physical button, for example, located on the steering wheel 14.

[0092] When indicator 211 is displayed according to the second graphic representation (corresponding to the current deactivated state), a displayed graphic object is configured to automatically activate the stability control and traction control function. Confirmation of the switch to automatic activation mode is obtained, for example, by touching this graphic object (e.g., a button with two states: one corresponding to automatic deactivation activated and the other to automatic deactivation deactivated), by voice command, or by activating a physical button, for example, on the steering wheel 14.

[0093] Validating the activation or deactivation of the automatic mode results in a change in the display of the signal indicator, which changes from the first graphic representation to the second graphic representation, or vice versa, depending on whether the automatic deactivation of the function or the automatic activation of the function is validated, respectively.

[0094] The second graphic content further includes one or more other graphic objects according to various particular embodiments, this or these other graphic objects being adapted to personalize the CDS system or the control of the CDS system.
